Abstract
The invention discloses a biodegradable water-based woodenware coating and a preparation method thereof. The biodegradable water-based woodenware coating comprises the following components in percentage by weight: 40 to 70 percent of biodegradable aqueous polyurethane emulsion, 5 to 25 percent of titanium dioxide, 0 to 15 percent of talcpowder, 0 to 25 percent of calcium carbonate, 1.0 to 2.0 percent of biodegradable film forming auxiliary, 0.5 to 2.0 percent of dispersant, 0.1 to 0.5 percent of antifoaming agent, 0.1 to 0.2 percent of bactericide, 0.1 to 0.2 percent of wetting agent, 0.1 to 0.2 percent of PH value regulator, 0.1 to 0.5 percent of thickening agent and 5 to 15 percent of water. The biodegradable water-based woodenware coating provided by the invention has the advantages of environmental friendliness, odorlessness, high drying speed and biodegradability, and is diluted by the water.
Description
Technical field
The present invention relates to a kind of woodwork coating, be specially the biodegradable water-borne wood coating of a kind of woodwork.
Technical background
At present, some flourishing woodwork importers are arranged, shorter to some work-ing lifes, change frequent woodwork, as interim exhibition booth etc., not only require the product environmental protection, also biodegradable, so that can very fast degraded under microbial process after product use to finish, to reduce behind the product abandonment pollution to environment.Therefore, the coating when this just requires the product application is not only wanted environmental protection, and is also biodegradable.Water-borne wood coating is the woodwork coating of a class environmental protection, can satisfy its feature of environmental protection requirement, but the current water-borne wood coating overwhelming majority is water soluble acrylic acid or water-based polyurethane, does not have a biological degradability.Although biodegradation technique had been widely used among the daily life in recent years, as disposable bowls and chopsticks, convenient bag, packing box etc., it is mainly plastics.The major technique characteristics be starch with readily biodegradable to modifying plastics, " biodegradable starch-containing resin combination and goods and the preparation method's " who announces as CN1916062A technology.In paint field, though biodegradable polymkeric substance has document to look into, as " aqueous liquid dispersion of at least a biodegradable polymkeric substance " that CN1613913A announces, it can be used for printing ink, coating, but how to use, uses the not explanation in which kind of field in coating.And because coating requirement for a long time is to need " long-effective protection ", this just requires polymkeric substance is not labile, and therefore, the application of this Biodegradable material in coating is still blank.
Summary of the invention
